Ehrenfest's theorem revisited, Henryk Arodź VIDEO
The beginning of the talk is devoted to the question what is the essence of the distinction between classical and quantum theories. Next, I point out certain important feature of quantum mechanical wave packets, which alleviates the need for the often postulated sharp divide into the classical and the quantum. In the main part of the talk several versions of Ehrenfest's theorem are outlined, including a relativistic one.
